OBJECT Cervical total disc replacement (CTDR) represents a relatively novel procedure intended to address some of the shortcomings associated with anterior cervical discectomy and fusion (ACDF) by preserving motion at the treated level. This prospective, randomized, multicenter study evaluates the safety and efficacy of a new metal-on-metal CTDR implant(More)
Microglia are the resident tissue macrophages of the central nervous system. They are rapidly activated by a variety of insults; and recently, receptors linked to cytoplasmic Ca(2+) signals have been implicated in such events. One potential class of receptors are those recognizing lysophosphatidic acid (LPA). LPA is a phospholipid signaling molecule that(More)
Oligodendrocytes are the myelin forming glial cells of the CNS and are known to express receptors linked to ion channels and intracellular second messenger cascades. In this paper, we describe the intracellular calcium responses of cells from the oligodendrocyte lineage to application of lysophosphatidic acid (LPA), a naturally occurring, growth factor-like(More)
BACKGROUND Anorexia nervosa (AN) is a serious psychiatric illness associated with significant morbidity and mortality. There is little empirical support for specific treatments and new approaches are sorely needed. This two-site study aimed to determine whether olanzapine is superior to placebo in increasing body mass index (BMI) and improving psychological(More)
BACKGROUND Anterior cervical fusion, an established procedure to treat cervical radiculopathy, sacrifices the natural function of the disc, while placing increased stresses on adjacent spinal levels. In contrast, the cervical total disc replacement (cTDR) maintains motion and decreases adjacent-level stresses. The purpose of this study was to investigate(More)
Infection of a prosthetic joint is uncommon in standard primary arthroplasty, occurring in 1%-2% of all cases.1,2 Recommendations for treatment differ depending on the time-course of the infection, the infecting organism, whether the implant is well-fixed, and the patient’s health.3,4 The most common organism cultured in a septic total knee arthroplasty(More)
STUDY DESIGN Analysis of prospectively collected radiographic data. OBJECTIVE To investigate the influence of preoperative index-level range of motion (ROM) and disc height on postoperative ROM after cervical total disc arthroplasty (TDA) using compressible disc prostheses. SUMMARY OF BACKGROUND DATA Clinical studies demonstrate benefits of motion(More)
BACKGROUND Trinity Evolution® cellular bone allograft (TE) possesses the osteogenic, osteoinductive, and osteoconductive elements essential for bone healing. The purpose of this study is to evaluate the radiographic and clinical outcomes when TE is used as a graft extender in combination with locally derived bone in one- and two-level instrumented lumbar(More)
